Agastache are incredibly useful for clouds of colour through the summer months. 'Summer Sky' has tons of lavender-blue flowers with purple sepals that bloom all summer into fall. Up to two feet tall with bright green, fragrant foliage. The Summer Series have sepals that remain in colour and do not brown like other agastache giving these cultivars a much longer season of interest. Even without a single flower there is still colour! Sun, dry soil.
